Lock has been compared to Favre and I think that might be a good way to show that Lock can improve and flourish in the right system. Cut down on turnovers and improve his mechanics (eg feet). Improve pre snap reads and he has a shot of sticking around in the NFL for a long time.
These days QBs are playing longer in the NFL and experience matters a lot more because of it. Which is why being a journeyman until you receive a starting shot is increasingly becoming more common than a rarity these days.
I really like your spiel if it was written two years ago. I think Lock has improved beyond what his Denver reputation had revealed. I'm not seeing happy feet. I'm seeing a guy that efficiently sidesteps pressure as if it has been rehearsed in his mind, keeping his eyes downfield, and then stepping forward into his throws. Farve had unreal arm strength, and it gave him such a false sense of security that he routinely threw off of his back foot or across his body and managed to pull it off with an impressive level of success (but his bad mechanics were still creating a turnover concern). I'm not seeing any of that from Lock. I'm seeing a guy that confidently repositions within the pocket, with little wasted movement, but still employs a great throwing motion. What really sticks out is his accuracy. His touchdown throw to Easop Winston Jr against the Vikings was a laser shot that was thrown within a very small window, perfectly timed and placed. It was easily the most impressive throw by a Seattle quarterback (or in my opinion, compared to anyone else in the league) during this 2023 preseason. Considering that Seattle ranked 27th in Red Zone efficiency last year, I'm not quite sure why people aren't raving more about that particular red zone play. It is certainly a play worth taking a second look at before passing judgment.
Lock's consistency has been rock solid this preseason, but similar in context to the preseason hype about Jordan Love, we need to see it when opposing teams are disguising their coverages and are using well-rehearsed game plans. Similarly, this is all that Lock has left to show, and barring injury, we aren't going to be able to see it. We can only trust what are eyes have shown us in preseason and my eyes have seen plenty enough. I would remain very confident if he were forced to finish the season for us.
